“Which Dan Patrick should we trust?” a narrator says as the 30-second spot begins, showing side-by-side two clips from the candidates’ debate last month. In one of them, Patrick, a state senator from Houston, says he’s “really concerned about the dropout rate in our inner cities” and in the other, he references his support for the Legislature’s decision to cut $5.4 billion from public schools in 2011.

The ad goes on to cite The Dallas Morning News editorial board’s endorsement of Van de Putte, which said some Republicans describe Patrick as “untrustworthy.”

“Party labels aside, more Texans are voting for the candidate they can trust,” the narrator says as the ad turns it attention from Patrick to Van de Putte, a state senator from San Antonio. The narrator then touts Van de Putte’s efforts to help veterans — she chairs the Veteran Affairs Committee — roll back the education cuts and put a “college education within reach of more working families.”

Titled “Matter of Trust,” the commercial will air in “select markets across the state,” according to Van de Putte’s campaign.

Less than an hour after her team released the ad, Patrick put out his own commercial focused on education.
